The Adveco PPN and PPS ranges are packaged plate heat exchanger systems with heat transfer capacities from 100 to 600 kW, and have been designed to provide an instantaneous (PPN) or semi-storage (PPS) supply of domestic hot water to a building.
Constructed from gasketed stainless steel and supplied pre-assembled with pumps, pipework, controls and valves on a metal skid base, the PPN and PPS ranges are WRAS approved products that are suitable for use with DHW systems up to 99°C and 6-10 bar.
Each range incorporates a 24 Volt controls system including a digital LED display of system temperature and setpoint, temperature controllers, volt-free contacts for BMS input and output signals, and is additionally available with either a single or twin-head pump arrangement.
The Advantages of Packaged Plate Heat Exchangers
Plate heat exchangers can be employed as a system break between old and new heating systems; used as a separation between systems due to pressure limitations or as an integration with renewables. Consisting of an alternating ‘sandwich’ of thin hollow metal sheets with passageways for different sources of liquid – for example, one with heating water and the other with domestic hot water (DHW). The plates keep the fluids separated, and as it spreads across the planes of the adjacent plate heat is exchanged.
Being supplied pre-assembled reduces design requirements and on-site assembly time for the M&E installer, supporting simple separation or pressure break systems, as well as systems with different temperature requirements between ‘side one’ and ‘side two’. The proven design guarantees a fast response to changes in the DHW system demand, plus accurate and close temperature control with easy to use purpose-built integrated controls.
Adveco Packaged Plate Heat Exchangers are compact, despite the extremely large surface area for heat exchange, so are easy to locate and access within the plant room for maintenance. Smooth surfaces with high turbulence created by the complex pattern of passageways within the plates help to also create a self-cleaning action for less fouling and scaling.
Water content is also low (so there is less water to treat periodically) and fast-moving under pressure. With no static water bacterial growth within the plate system is virtually eliminated. The gasketed design means the system is also easy to disassemble to clean and maintain.
Critically, the gasketed design ensures there is no cross-contamination between the two fluids, so it is a perfect response when integrating new and old systems. By easily adding extra plates, a system can be expanded to meet the specific requirements of a project or application.
